Reads a single byte to the local Tx buffer.
- BYTE	Index
Byte to read, range 0 - 31
- BYTE	Value
- VOID	Return

	FlushRx
Tells the RF module to flush the contents of the receive buffer. Returns the status from sending the command.
- BYTE	Return

	ReadRxFifo
Reads the Rx FIFO buffer into a local buffer. Use the ReadBuffer macro to collect the individual data bytes.
- BYTE	NumBytes
Number of bytes to try and read from the FIFO Range 1-32
- VOID	Return

	WriteTxFifo
Writes the contents of the local Tx buffer to the Transmit FIFO.
- BYTE	NumBytes
Number of bytes to write to the FIFO, Range 1 - 32
- VOID	Return

	FlushTx
Tells the RF module to flush the contents of the transmit buffer. Returns the status from sending the command.
- BYTE	Return

	CheckRX
Check the Rx FIFO status register for any new data. Returns 0 = No data Returns 1 = New data available
- BYTE	Return

	ReadRegister

Writes a single byte to the selected register. Returns the status of the write command.
- BYTE	Reg
Register address to access
- BYTE	Value
- BYTE	Return

	Initialise
Starts up and configures the RF module ready for use. The macro will return a value greater then 0 if the module has been started correctly, otherwise the macro will return a 0.
- UINT	Return

	AutoMoveToPositionInt
Automatically moves towards the new 16-bit position at a fixed rate determined by the AutoMoveSpeed.

	Initialise
Sets up the servo motor interrupts
- VOID	Return

	WriteLEDs
Allows control of all 8-LEDs on the front of the Formula Flowcode.
- BYTE	LED_Byte
- VOID	Return

	Initialise
Starts up the formula flowcode PWM for motor control and performs the wait for button press
- VOID	Return
